I'm no expert, but I do it like this: Define the text frame on the
next page, click the previous text frame to activate it as a starting
frame, click the "link text frames button" (right next to the text
editor button) to activate link mode, then click the text frame to
link to, and you will see the text flow into that text frame
immediately. Also you will see the linking arrow between the two
frames in case you the didn't deactivate this feature. Next don't
forget to deactivate the "text link button", otherwise you will get an
error message with the next click. The best would be to activate the
arrow ("activate object"-) button.
